cAsEMeNT-ADJUSTER.

` Application led August 1,

To all wkomz't may concern."

Be it know-n that L HENRYGL VoIGH'r, a citizen of the United States of America, residing at New Haven,` Connecticut, have invented a new and useful Casement-Adjuster', of which the followingv is a specilication.

My invention 'relates Aparticularly to a friction device for holding a` movable part indifferent adjusted positions with Vrelation to a relatively. stationary Ipart and I have illustrated the inventionf as applied to a easement adjuster. 'y The main object of the invention is to provide a simple and inexpensive form of device which mayA be -readily adjusted to afford varying degrees of resistance to movement and which is durableand which will noi-.scratch or mar the extensible eletherefolx ments.

In its simplest form the principal elements of the invention comprise two relatively telescopic members with a special. friction device surrounding the inner member and clamped with relation to-it by means of a device which serves also as a housing' Figure 1u is a plan View and partial secvtion showing the invention as applied to a 30 i front view of Fig. y5 is a side vlew of the clampingelenient.

Fig. 6, shows a modified member.

Fig. 7, is a detail view showing two gripform of. gripping l ping members.

In the form shown the rod -6 is hinged to the swinging member 7. The tube 8 is hinged to the relatively stationary part 9. The clamping member 10 is. preferably formed of a non-metallic substance Suchas.'

relatively hard fiber with a longitudinal passage 1l permitting the ily slipped on the rod 6. The member 12 is interiorly threaded at` one endso as'to screw onto the outer end of the tube 8. The other Vend has a passage device to be readfor therod 6 and isprovided with a shoul- Specification of Letters Fatent. Patented Dec.' 30., 1919.

Y dei' 13' to engage one end ofthe member 10.

The outer end of the tube 8 has an oppositely facing'shoulder' 14 for engagement with the opposite end of the memberY l0. One or each ofthe ends of the member l0 is off-set' from the main body or beveled as at 15 and 16 so that when the member 12 is screwed on -tothe end ofthe tube 8, the

clamping member 10 is caught between the pressure of the shoulders 13 and 14 and tilted so as to frictionally grip the surface of the rod. By tightening up on the mem ber 12 more or less, greater or less friei may be produced and consequently b eater' or less resistance to movement of lthe rod 6 relative to the tube 8. In factit is possible to grip the parts so as to entirely 1 prevent relative movement byl the exercise of ordinary pressure. A clamp nut 18 may be provided if desiredto prevent the' mem- Y ber l2 from working loose, ordinarily how ever, this Lis notrequired as4 the friction produced by the member 10 is suicient to prevent accidental displacement'` The member `10 vmay be split as indicated' at 17 in which case it will be `more readily deformable. Such .expedient may be used ,when the material is hardfor insta ice if metal is used. I

. wo members 10.a and 10b may be used as indicated in Fig. 7, one bearing, against the other soK as to increase the gripping eifect.

Although the device shown 1s applied tov Aa easement adjuster, it will be-appar'ent that the essentialelemen-ts of-the invention are applicable to many otheruses where a friction device of this character l claim :-n .y
